Ex15.1, 22
Two dice, one blue and one grey, are thrown at the same time.
(i) Write down all the possible outcomes and complete the following table:
Total number of outcomes = 36
Ex15.1, 22
(ii) A student argues that ‘there are 11 possible outcomes 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Therefore, each of them has a probability 1/11. Do you agree with this argument?
From the completed table
It can be seen that each term does not have a probability of 1/11
Therefore, it is an incorrect argument.
